More than 1200 drivers have been caught by speed cameras adjusted for new 40km/h limits in Canberra's city centre on the first day of operation.
The three cameras caught 1259 vehicles speeding in the first 24 hours since the cameras were switched over to begin issuing fines on Monday.
More than 20,000 drivers were caught by the cameras in a two-week period before fines were issued as part of efforts to inform road users of the changed limits on parts of Northbourne Avenue and Barry Drive.
The 1259 speeding images are yet to be adjudicated, but between 60 and 70 per cent are likely to receive fines.
New limits, which dropped speeds by 20km/h, were introduced three months ago as part of the ACT government's road safety strategy.
The cameras capture northbound traffic at the intersections of Northbourne Avenue and Barry Drive, southbound traffic at Northbourne Avenue and London Circuit and westbound traffic at Barry Drive and Marcus Clarke Street.
Access Canberra executive branch manager Josh Rynehart last week said the average speed going past the cameras was below 40km/h, which meant most drivers were following the rules - but others still needed to change their behaviour.
"It's disappointing to see how many people are coming through [speeding]. The speed was reduced for a road safety perspective, and it is concerning to see how many people appear to continue to drive above the speed limit," Mr Rynehart said.
Mr Rynehart said speed limits could change in different areas and it was a driver's responsibility to be aware of road conditions.
"It's the responsibility of everyone when you're driving, to be aware of the environment that you're driving in," he said.
